LOCK;

Application filed `.Tune 26, 1922. Serial No. 570,779.

To all 107mm t may concer/li Be it known that l, Vrc'ron VVAizNnLo, acitizen of the United States of America, residing at Grand Rapids, inthe county of Kent and State of Michigan, have invented certain new anduseful Improvements in Locks, of which the following is a specification.

This invention relates to certain new and useful improvements in locks,and has particular reference to a lock embodying a casing and a hingedshackle bolt supported thereon with a tensioned'lockingdogr engaging thekeeper end of the shackle bolt for retaining the same in locked positionrelative to the casing.

The primary object of the invention rcsides in the provision of a lockhaving the peculiar releasing mechanism for the shackle bolt, theshackle bolt being released by a hingedly mounted bar simulatinga bracebar for the lock casing, said casing being provided with a key holeopening that does not enter into the operation of the shackle bolt.

lfVith the above general objects in view and others that' will becomeapparent as the nature of the invention is better understood, the sameconsists of the novel form, combination and arrangement of partshereinafter more fully described, shown in the accompanying drawing andclaimed.

ln the drawing, wherein like reference characters designatecorresponding parts throughout the several views,

Figure i is a sectional view taken on line lV-IV of Fig. 1 showing thelug carried by the ope vating bar for releasing the shackle bolt keeper,and

Figure 5 is a sectional view taken on line V-V of Fig.` 1.

Referring more in detail to the accompanying drawing, there isillustrated a padlock embodying' a casing comprising a rear wall 1,`side and upper and lower end walls 2 and 3 respectively, the upper endwall being cut away as at i and 5 respectively `to accommodate thepivotal mounting of one end of the shackle bolt 6 and also providing anopeningfor receiving,r the swinging end of said shacklebolt. A cover 7is secured to the body casing by corner pins 8 shown more through' thecover and body of the lock as rshown in Fig. 5 and anchored by bracebars 9 arranged adjacent opposite endsv of the lock casinO.

clearly in Fig. 2, the corner pins extending The shzckle bolt 6 ispivotally mounted 12, the leg` 13 thereof carrying a keeper hook 14 forengagement with lthe hook 11 upon the adjacent swinging` end of the`shackle bolt 6, the other leg- 15 of' the bell crank keeper levercarrying a vdepending lug 16 for purposes presently to appear. A bandspring bent into substantially V-shaped formation is disposed within thecasing, the loop 17 thereof being' supported upon the pin 18, one leg 19of said spring havingf the free end thereof extendingif intothebifurcated end of the shackle bolt 6, and engagin g the pin 20 forincreasing tension thereof, the other leg 21 of said spring engagingirthe adjacent rear face of the keeper lever leg 13 as shown in Fig. 2,moving the keeper lever upon its pivot pin 12, which movement is limitedby the leg 13 engaging the pin 22.

A pivotally mounted bar 23 mounted upon the lock casing cover 7 adjacentone end thereof, in simulation of a brace bar 9 is pivoted adjacent theupper end thereof upon the pin 24 and carries a false retaining pin 25in the lower swinging end thereof. T he casing' cover 7 is slotted as at26, shown more clearly in Figi. 5, a finger 27 carried by the inner faceof the pivoted bar 23 extending through said slot 26 for engagement withthe depending lug or finger upon the lower leg 15 of the bell crankkeeper lever. The

and the inner end 10 of said shackle lock casing cover 17 is providedwith a'key hole opening 28 tending to confuse and in no 'manner effectan operation of the lock.

. Assuming that the shackle bolt Gis in the locked position shown inFig. 1, and it being desired to release the same to permit shift;-ing'to the dotted line position shown in Fig. 2, the pivoted bar 23 is'shifted to the dotted line position shown in Fig. 1, causing the finger27 carried thereby to engage the lug 1,6 upon the bell crank keeperlever to shift said lever upon its pivot pin 12 and release the keeperhook 14 from engagement with the hook 11 upon the free swinging end ofsaid shackle bolt. `The outer end ofthe y spring arm 19 beingundertension by engaging ,the pin 20, as shown in Fig. 2, said spring arm 19engaging the bifurcated end 10 of the shackle bolt will shift theshackle bolt upon the pin 8 and cause the same to vmoveto the dottedline position, and when Y so disposed, and when pressure is relievedupon the pivoted bar 23, the spring armv 21 engaging the upper leg 13 ofthe keeper lever will restore the keeper lever to its set 'posi tionengaging the stop pin 22 and causing the ,lug 1G carried by the lowerleg 15 to if" `shiftthe nger27 .and pivoted bar 23 to its ters into' theoperation of said lock.

plicated nature, there being comparatively` few parts embodying'theoperating mechanism thereof .andsuch partsbeingofa na-l ture 'that arenot liable to damage.

lVhile there is'herein shown and described a the preferred embodiment ofthe present invention, it is nevertheless to be understood that minorchanges may be made therein without departing'from the Aspirit and scopeof the invention as claimed.

What is claimed as new is :e

lIn a lock of the type described, va casing,

two pairsl off longitudinally extending bars carried by said casing,each pair beingpositioned Von opposite faces of the casing and adjacentthe side walls thereof, one of the vbars carried by the front facev ofsaid casing beingpivotally attached thereto, a shackle bolt having abifurcated end pivoted within the casing and having a hook upon theother end adapted toenter the casing, a tensioned` keeper lever pivotedwithin theicasing engaging the hook end of the shacklebolt, and meansfor shifting the keeper lever to free the same from engagement with saidshackle bolt hook, vsaid means comprising a finger 'carried by said l,pivoted bar extending through a slot provided 1n said casingand.engaging with said keeper lever for shifting thesame to free the hookend ofthe shackle bolt` the tensioned means foi-'said keeperleverembodying asubstantiallyV-shaped flat
